Los pesos de tres recipientes son proporcionales a los números 8, 12 y 15 si el peso total contenido en los tres asciende a 2100 kg. ¿Cuánto pesa el menor de los tres?

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

hi there, i would be interested to you with your test, may you add the questions and answer options.

- : )

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
